Introduction

In mathematics, expressions are a combination of numbers, variables, and mathematical operations that can be evaluated to produce a result. Evaluating an expression involves following the order of operations (PEMDAS) and simplifying the expression to obtain a final value. In this article, we will evaluate the expression (9)2+5(\sqrt{9})^2 + 5 and explore the concepts of square roots and exponents.

Understanding Square Roots

A square root of a number is a value that, when multiplied by itself, gives the original number. For example, the square root of 16 is 4, because 4×4=164 \times 4 = 16. The square root of a number is denoted by the symbol \sqrt{}. In the given expression, we have 9\sqrt{9}, which means we need to find the value of xx such that x×x=9x \times x = 9.

Evaluating the Square Root

To evaluate the square root of 9, we need to find the value of xx such that x×x=9x \times x = 9. We know that 3×3=93 \times 3 = 9, so the square root of 9 is 3. Therefore, 9=3\sqrt{9} = 3.

Understanding Exponents

An exponent is a small number that is raised to a power, indicating how many times the base number should be multiplied by itself. For example, 232^3 means 2 multiplied by itself 3 times, which is equal to 2×2×2=82 \times 2 \times 2 = 8. In the given expression, we have (9)2(\sqrt{9})^2, which means we need to raise the value of 9\sqrt{9} to the power of 2.

Evaluating the Exponent

To evaluate the exponent (9)2(\sqrt{9})^2, we need to raise the value of 9\sqrt{9} to the power of 2. We already know that 9=3\sqrt{9} = 3, so (9)2=32(\sqrt{9})^2 = 3^2. To evaluate 323^2, we need to multiply 3 by itself 2 times, which is equal to 3×3=93 \times 3 = 9.

Adding 5 to the Result

Now that we have evaluated the exponent (9)2(\sqrt{9})^2, we need to add 5 to the result. We already know that (9)2=9(\sqrt{9})^2 = 9, so adding 5 to the result gives us 9+5=149 + 5 = 14.

Conclusion

In conclusion, evaluating the expression (9)2+5(\sqrt{9})^2 + 5 involves understanding the concepts of square roots and exponents. We found that 9=3\sqrt{9} = 3, and then raised 3 to the power of 2 to get 9. Finally, we added 5 to the result to get 14. Therefore, the final answer to the expression is 14.

Q&A

Q: What is the square root of 16?

A: The square root of 16 is 4, because 4×4=164 \times 4 = 16.

Q: What is the value of (25)2(\sqrt{25})^2?

A: The value of (25)2(\sqrt{25})^2 is 25, because 25=5\sqrt{25} = 5 and 52=255^2 = 25.

Q: What is the final answer to the expression (36)2+3(\sqrt{36})^2 + 3?

A: The final answer to the expression (36)2+3(\sqrt{36})^2 + 3 is 39. We know that 36=6\sqrt{36} = 6, so (36)2=62=36(\sqrt{36})^2 = 6^2 = 36. Adding 3 to the result gives us 36+3=3936 + 3 = 39.

Q: What is the value of (49)3(\sqrt{49})^3?

A: The value of (49)3(\sqrt{49})^3 is 343. We know that 49=7\sqrt{49} = 7, so (49)3=73=7×7×7=343(\sqrt{49})^3 = 7^3 = 7 \times 7 \times 7 = 343.

Q: What is the final answer to the expression (81)2+2(\sqrt{81})^2 + 2?

A: The final answer to the expression (81)2+2(\sqrt{81})^2 + 2 is 83. We know that 81=9\sqrt{81} = 9, so (81)2=92=81(\sqrt{81})^2 = 9^2 = 81. Adding 2 to the result gives us 81+2=8381 + 2 = 83.

Q: What is the value of (4)4(\sqrt{4})^4?

A: The value of (4)4(\sqrt{4})^4 is 16. We know that 4=2\sqrt{4} = 2, so (4)4=24=2×2×2×2=16(\sqrt{4})^4 = 2^4 = 2 \times 2 \times 2 \times 2 = 16.
